摘要: 以Nisin和乳酸作为参照,采用本试验室获得的重组牛乳铁蛋白肽对生鲜猪肉进行保藏试验。生鲜猪肉浸沾并真空包装后置于4℃下存放,测定肉样的微生物数、抗氧化值(TBA)、pH值、肉的红度值(Huntera)及感官评价。结果显示,重组的牛乳铁蛋白肽保鲜效果优于Nisin组,接近乳酸组。其保鲜期可达到19d。

Abstract: Fresh raw pork was treated with natural preservative solution made of recombinant bovine lactoferrin N-terminal peptide, Nisin and lactic acid. Raw pork were dipped in peptide, Nisin and lactic acid with concentration 1% respectively, then vacuum-packaged and placed at 4℃, to assay microbial count, TBA value, pH value, Hunter a* and sensory value respectively. Results presented that the recombinant bovine lactoferrin N-terminal peptide shows better antimicrobial activity than the Nisinand close to the result of lactic acid treatment. The pork can be kept well up to 19d at 4℃.
